Re: Ask HN: I’m an FCC Commissioner proposing regulation of IoT security updates

As a firmware engineer, I'm one of the people who actually writes the code that goes inside the IoT devices. I'm very interested in what the FCC might be able to do here. How does the FCC define a security flaw? Would updates only be distributed when there is a flaw that needs fixing? Remote update mechanisms can themselves present security problems in some domains. Thus, some devices should only be updatable if the…

This is a good point, some IoT devices really can't be designed to be physically serviceable, while still remaining reasonably compact, e.g. those that need very high levels of water resistance, especially saltwater resistance. And adding any remote update mechanism at all would more then likely decrease overall security. So there actually should be a counter mandate too, for devices that are impractical to design to…

It sounds like you're looking for a carve out so you don't have to upgrade your devices to have a modern microcontroller that supports remote updates and are using saltwater as a scary thing so no one challenges you on it.

You can conformal coat a ESP32 with a sensor and battery and a wireless charger, and get remote updating. If hobbyists are doing that without commercial backing, what industry experts like you have access to must be even better.

Good question. The Notice of Proposed Rulemaking has a Legal Authority section that discusses this issue https://www.fcc.gov/document/fcc-proposes-cybersecurity-labe... . I also touch on it here https://news.ycombinator.com/item?id=37393316

To expand on this, since it's not explicit in Marco's comment: The statutory authority is section 302(a) of the Communications Act, which authorizes the FCC to regulate devices that can interfere with radio communication. Their reasoning is that IOT devices fit this category, so regulations on security updates are within scope. Full quote from the notice of proposed rulemaking: "In particular, section 302(a) of the C…

Thank you very much for reading. It was the first, and last time, I ever took place in the public process and political action. https://www.computerworld.com/article/2993112/vint-cerf-and-... We were within months of delivering a massive RFC8290-based fix for wifi performance and we´d been bricking routers left and right... and then got in a whole bunch that we could not modify... due to that proposed regulation... I…

Thanks again -- will review both links (especially the latter!) The FCC hasn't traditionally been a cybersecurity agency and will, most likely, never really be one; however, we can certainly do things through rules to empower experts, the public, and the agencies with cybersecurity expertise. If that one thing is all you ever did at the FCC, sounds like the public owes you a big debt of gratitude.

Where cybersecurity is a critical aspect of being able to communicate in our modern world, I urge you to rethink that. I can't go by BestBuy and buy a TV that radiates rf noise all over the place, interrupting communications, but I can buy an IoT device that will get hacked and radiate packets all over the Internet and become part of a botnet, interrupting communications.

> Remote update mechanisms can themselves present security problems in some domains. Not really if done right to be fair. It's just a matter of implementing a signature verification of the firmware updates that are installed on the device. > IoT is making its way into defense and enterprise environments where reliability is a matter of national security. If it's a matter of national security surely you don't use IoT…

> It's just a matter of implementing a signature verification

correctly

With rollback protection, a chain of signing keys to allow revocation, time stamping, correct parsing, enough scratch space to hold an entire separate image in A/B, enough processing power to verify image signatures, etc etc.

Doing this well is very hard. Given most IoT vendors don’t yet know how to prevent XSS, there’s near zero chance they’ll get updates correct in the next decade without solid open source frameworks to leverage.

Also, security researchers should have strong legal protections; they should be given the benefit of the doubt at every turn. Currently, researchers are sometimes threatened with decades in prison for testing the security of websites or devices. If they act in good faith as researchers, this should never happen. This is literally a national security issue. We currently stifle security research on essential IoT device…

This might be an unpopular opinion but I respectfully do not see it that way. I agree with promoting security for IoT devices, but there needs to be consent from the company being probed for vulnerabilities or else I find it hard to consider it legitimate research, regardless of intent. I dont think anyone would like it very much if someone came to their house and documented all the ways to rob it they could find, ev…

White Hat: Can I hack your website and services?

Company: No we are super secure! No trying to find vulnerabilities.

Black Hat: lol sells company data

Is there any way to get people a way to opt out of unnecessary internet connectivity? It seems to be spreading to include functionality that shouldn't require internet connectivity to begin with, like basic data storage and controls from a local network.

>If the attacker has total control, then all bets are off no matter what mechanisms you put in first. Great, so we now agree that it's important to keep the system patched and up to date.

That depends on updates never introducing new vulnerabilities.

Well, lots of people have been not-buying liquorice their whole life, but nothing's changing. The market for liquorice candy is alive and well. Less snarky: if other people still want to buy certain products, manufacturers will provide. But that's not a bad thing. Different folks have different preferences.

Why did you suggest not-buying as a better action than regulation if you acknowledge that it doesn't work? Are you a manufacturer of low-quality IoT devices? People don't prefer insecure devices, they just want convenience and manufacturers are not being upfront about how dangerous these "convenient" devices are. Ergo, regulation.

Convenience and low price are legitimate preferences, even if you disagree.

Insecure IOT has the huge externality of providing muscle to criminal botnets, though.

Tax them, then?

Indeed. And that's good.

It's good that consumers have much less power in context of forcing manufacturers to the described choice?

What do you mean by less power? It's different.

One manufacturer can't force you to buy stuff you don't want, nor ban you from buying from a different manufacturer that does what you want.

(In contrast with the FCC, which has a lot of power over you, by banning you from buying what you want.)
